On Monday, mourners at the candlelight vigil remembered a lovable teenager who loved sports and education.

"At lunch he would be the first one to greet me and say, 'Hi.' He would hug me and say, 'Make sure you go to class,'" said Shanniella Rhoden, 16, who went to school with Brooks. "When I heard he died I didn't know what to do. I still think it's a dream."

Kemar was shot in the head just steps from the tennis court where he often played. He was with two other young men when it started to rain. The three ran for cover under a gazebo, and that's when the shots rang out.

The two friends ran away but Kemar was struck by an errant bullet in the back of the head, police sources said.

"The detectives found a witness to a shooting into the park at about 8:00 the night before, before the young man's body was found by his father," Kelly said at an unrelated news conference in Harlem. "The individual is described as a person wearing a hoodie firing rounds into an area near the basketball court, which is sort of in line with the gazebo."

Kelly added that cops found a handgun Monday night, though it was unclear if it was the weapon used in the fatal shooting.

No one has been arrested. A detective who spoke at the vigil said cops "were not going to stop working on this."

The NYPD is offering a $12,000 reward for information leading to an arrest. Tipsters are asked to contact Crimes Stoppers at 1-800-577-TIPS, where callers can remain anonymous.
